Description

Hex Bolt and Nuts can be used in a wide variety of building and industrial applications where joining of materials is required.

At Demak we only supply our M10 Gal Hex bolts with a full thread so they can be used with the Klevaklip Adjustable Joist Support. If you forgot to order them with your joist support brackets then you’ve come to the right place!

Remember, you will need 2 bolts, 2 washers and 4 nuts for every 1 bracket.

See this handy chart below to work out the bolt length you need to suit your job.
